President Donald Trump’s Inauguration Day was marred by noisy demonstrations, shoving matches and sporadic clashes with cops that resulted in more than 200 arrests.

Three-thousand members of local, state and federal law enforcement — backed by 5,000 National Guard members and police officers from as far away as New Jersey — patrolled the streets as the evening’s festivities got under way and the legions of protesters still seething over the Manhattan mogul’s unexpected victory threatened more disruptions.

Acting Police Chief Peter Newsham said that by around 6:30 p.m. ET things had calmed down, but authorities were still monitoring several groups.

At the same time, police are preparing for the Women’s March on Washington set for Saturday that is expected to draw 200,000 protesters — a number that inaugural historian Jim Bendat said could break records.
